Natural
History Web Site Data Base
by Tom Schweich and Barbara Ertter
|
Date Last Updated: January 20, 2000 |
This document describes the data base and associated program code that was originally designed to prepare the Carl A. Purpus site on the World Wide Web. For that web site we needed to be able to publish articles either by or about Purpus, list all his collections, list types described from his collections, and list all sorts of other things, such as locations, images, etc.
In addition, it was necessary to cross-reference each type of information to other occurrences of related information. For example, we needed a way to keep a two-way cross-reference between Purpus' field reports and the list of locations he visited. We also wanted the cross-reference to be dynamic, or process-able, so new links could be added as new information became available.
As the Purpus web site developed, it became apparent that there were numerous applications for a data base of this type. For example, the lead author also has his own web site, which includes many of the same elements as the Purpus web site. Therefore the data base engine has been generalized to build any number of web sites, simply by changing the source of the data.

A Collection does not appear on the Collection Page unless there is a Determination and a Voucher.
Collections pages would be a good candidate for dynamic serving from a data base.
Locations would seem to be one candidate for dynamic HTML created as requested by the web server. In that process, though, consideration should be given to a single Location table, or gazetteer, which is common to several web sites. We already have multiple files of locations. There is the Jepson Place Name Index, the Purpus locations files, and my own Locations files on my eastern Mojave web site. When I build the Annie Alexander and Louise Kellogg web site, I would expect to build yet another file of Locations.
Also, so far, we have listed only the United States locations visited by Purpus. There are also many locations in the Sousa paper that are in Mexico. We may at some time need to expand gazetteer locations to include Mexico.
Each Location should be checked against G. N. I. S. before we list a link to there. Sending someone to G. N. I. S. where they learn that the Location is not there, would be considered a "broken link," one of the deadly web site sins. If the location file were implemented in a data base and generated dynamically, then a check against G. N. I. S. could be performed dynamically. The Location table (tblLocations) has a field (logTryGNIS) indicates whether a link should be prepared to G. N. I. S. An automated feature could set this field.
Types pages might be a good candidate for dynamic serving.

It should be possible to abbreviate the query string, and then contact a server that could expand the query, submit it to a data base server, and then report the results back, or allow the data base server to report the results back directly.

You need to lay out all the major elements of your web site independently of the data base. You need to figure out which are the "articles," the letters, locations, etc. Then you need to outline how you want to fit the articles together, and where on the various index pages you want to refer to the various pages.
The data base prepares the content pages; it does not structure the web site. You must provide the homepage and any intermediate pages.
When the Natural History Web Site Data Base starts the main menu is displayed.
One of the first operations you must do each time you use this database is to select a database you want to use. You select a database by clicking on the "Select Data Base" button of frmMain.
After you click OK, you are returned to the Main Menu.
Every Table has an associated Form to assist in data entry.
When Done is clicked, the data base returns to the Main Menu.
The Natural History Web Site Data Base is capable of preparing multiple web sites. There is one Table in the data base that contains information this is unique to each Web Site. This Table (tblDataBase) can be edited directly or edited using a Form (frmDataBase).
Enter a short name that you will use to refer to this data base, e.g., "Purpus" or "Mojave"
Enter the full path of the directory in which the data resides. Be sure to include the drive letter, but do not add a "/" or "\" at the end of the string. For example, e:\data\Purpus Work Area\Data Base
Enter the file name and extension of the data base in which the data resides, e.g., purpusdb4.mdb
Enter the full path of the directory where the Natural History Web Site Data Base should write the .html files, e.g., e:\data\PurpusWebSite
Enter the color that you would like to use as a default background color. If you don't specify a default background color the data base will supply #F6F6F0. This value is kept in strDBDefDefBGColor which is a global variable in Class Module: Form_frmMain.
Not used.
Content to be placed in <meta name="keywords" content="…"> tag.
Content to be placed in <meta name="description" content="…"> tag.
Default site author to be placed in the header of every article if the Author attribute is not specified for an Article. (Note: this function, while an excellent idea, has not been implemented yet.)
Default site copyright for each page on the web site. (Note: this function, while an excellent idea, has not been implemented yet.)
Site Rating. Not implemented.
Instructions for robots at this site. Not implemented.
The base of the full URL for the new location of this web site, if the web site has moved recently. If the value is specified, then a set of redirection .html files is written for every page in the web site. These files use the refresh Meta tag to refer users to the new web site, i.e., <META HTTP-EQUIV="Refresh" CONTENT="…">. The files are placed in e:/data/oldwebsite. The path is hard-coded in subroutine WrOldWebPage.
When this Form is closed, the data base returns to the Main Menu.
Does just that, closes the data base and exits Microsoft Access.
Clicking Build All Pages will cause the data base engine to create a complete web site. Watch the status area in the lower left corner for progress information. When complete, you are returned to the Main Menu.
The following tasks are arranged somewhat in a natural order of occurrence.

Entering Locations that begin with small letters seems to confuse the data base engine.

This web site consists of 22 types of entities:

· A Gazetteer is a collection of Location data across multiple sources. Each web site produced by this Web Site data base has a Geographical Index. The Gazatteer is the collection of all Locations across all Web Sites.
· A Page is a group of Paragraphs in an Article.
In the first case, Purpus collected Festuca ovina ssp. saximontana var. purpusiana at Farewell Gap twice, once in 1896 and again in 1897.
In the second case, Purpus collected the same plant, Penstemon icertus in two different locations in the same trip. These locations were Walker Pass and the Argus Mountains, which are about 50 km distant from each other.

2) For each Bibliography entry:
a) Opens rsttblBibEntry, to format the Bibliography reference.
b) Determine whether the Alternate Filetype should be used for the hyperlink to the bibliography entry. If the page number of the page containing the Topic of Literature Cited is greater than the maximum page for the Alternate File type (strMaxPgAltFT), then use the default page type.
Purpose: Make a list of Areas that include the Location being processed.
Called by: but_GWB_Locn_Click.
Operations:
Purpose: This subroutine searches through tblXref looking for Collections that were used in describing a Type.
Integer Used as a counter when stepping through the Cross Reference records in rsttblXrefPrv. rsttblXrefPrv Recordset A recordset in tblXref, local to SrcCollTypes, because there are often multiple recordsets open in tblXref.
Calls:
Search for Letters that referred to a location. Used by ExLocnList.
Used by ExArticles to insert a reference to a Letter into an Article.
This subroutine searches through tblXref looking for Links that relate to a Paragraph.
This subroutine searches through tblXref looking for Locations that relate to a Letter.
This subroutine searches through tblXref looking for Location(s) that refer to another Location.
This subroutine searches through tblXref looking for Locations that relate to a Paragraph. This routine is used by ExArticles to enter Location references in the Articles.

This subroutine searches through tblXref looking for Paragraphs that relate to a Location. Writes references in tblGazRef for Paragraphs that refer to Locations.
Called by: but_GWB_Locn_Click.
Procedure
1) Get a list of all the Paragraphs that relate to this Location (rsttblXref). Use a Select distinct because there may be more than one Cross Reference between a Paragraph and a Location.
2) For each Paragraph that refers to a Location.
a) Get the Title of the Article that contains the Paragraph.
b) Write out the Title.
c) Get the Page of the Article in which the Paragraph appears.
d) Figure out whether the Page uses the default page filetype or the alternate file type.
e) Build the link to the Article Paragraph. Also write the information into the list of Gazetteer references (tblGazRef).
Used by ExArticles to prepare a cross-reference between paragraphs.
1) Query tblXref for any Cross References with the current Paragraph.
2) If there are records found, Do for every Cross Reference found
a) Query tblArticles for the Stitle attribute
b) If there is no Stitle, query tblArticles for the Title attribute.
c) If the new title is different that the last title written, then write the new title out.
d) Query tblParagraphs for the Page number of the other Paragraph to which we are referring.
i) If we get just one reference then:
(1) Check tblArticles
to see whether the Alternate File Type (strCurAltFileType) should be used. (New: May 6, 2001)
(2) If it’s a non-road reference then format the link.
(3) If it’s a road reference then format the link another way.
ii) If we get something other than one reference, then throw up.
e) Take
the next Cross Reference from the query.

6/8/2000: Discovered that WrImageTlr was using groups 580 and 599. This should be an error as those groups are reserved for articles. It was probably a result of cloning code. Corrected the group numbers to 180 and 199, respectively.
This subroutine takes the
requested HTML, packs it into buffers, and writes the data to a file when the

There are times and places
where all you want an HTML page to do is go somewhere else.
This might happen because the
old page content was obsolete but you need to keep the link. Or because you
want to log the popularity of an incoming or outgoing ad banner response.
Here is the code for a
typical redirection page...
<HTML> <HEAD> <TITLE>Page Redirection example</TITLE> <META HTTP-EQUIV="Refresh" CONTENT="3;URL=http://www.xxx.com"> <META NAME="GENERATOR" CONTENT="Mozilla/3.0Gold (Win95; I) [Netscape]"> </HEAD> <BODY BGCOLOR="#FFFFFF"> <H2>This page is outdated. Click <A HREF="http://www.xxx.com">here</A> for the latest info or standby. </H2> </BODY> </HTML>
That <META
HTTP-EQUIV="Refresh" CONTENT="3;URL=http://www.xxx.com">
line does all the work. "Refresh" is the redirection command. The url
is where you want to go. And CONTENT is the approximate time delay in seconds.
Click here for a redirecting example
Your screen content should give an
alternative access means for an ancient or nonstandard browser. It should also
explain why the redirection is needed.
One gotcha: Using a time delay of zero
is bad news. First because you still will have the page display for a few
seconds while the new page is accessed. But worse because their browser back
arrow will no longer work!
With a zero time delay, the back arrow
goes back and the redirection goes immediately forward. Round and round. Give
enough delay time for a user reaction if they really want to go back.

Redirecting a Home Page to another URL
Redirecting your home page to
another URL may be achieved by creating a file
~info/www/people/loginname/index
with content
File=index.html
Redirect=URL
and running wndex within that
directory. This will redirect any request to your home page to URL.
As an example, you might want to
redirect your home page to the automatically generated business card page. This
may be achived by writing a file
File=index.html
Redirect=http://www.risc.uni-linz.ac.at/people/homepage.cgi?query=loginname
and running wndex.
